The version of `depcomp' supplied with sh-utils-2.0j does not work
correctly for DOS/Windows-style file names. The following Sed script
breaks if .deps/*.Tpo files include absolute file names with drive
letters:
sed 's/^[^:]*: / /' < "$tmpdepfile" >> "$depfile"
This happens because on DOS/Windows, "gcc -MD" produces the following
in, e.g., sh-utils-2.0j/lib/.deps/addext.Tpo:
e:/src/gnu/sh-utils-2.0j/lib/addext.o: \
e:/src/gnu/sh-utils-2.0j/lib/addext.c ../config.h \
e:/src/gnu/sh-utils-2.0j/lib/backupfile.h c:/usr/gcc/include/limits.h \
c:/usr/gcc/include/sys/types.h c:/usr/gcc/include/sys/djtypes.h \
c:/usr/gcc/include/string.h c:/usr/gcc/include/sys/movedata.h \
c:/usr/gcc/include/unistd.h
The first line above is supposed to be removed by the Sed script, but
that fails because the file name includes a colon.
The patch to depcomp which fixes this is below. It assumes that
\{m,n\} is supported by all versions of Sed.
